I have also turned parts of my Substack into a book (March 2026). 33 essays, 10 chapters, 3 stories you can’t read here, 0 subscribe buttons. It’s called “Thrive (Don’t Just Survive)” and it’s pay-what-you-want. If you’ve been reading along, you already know most of it. The book just puts it in order and adds some parts which I hadn’t told yet. Get it here.
